Multi-SIM Paging Feedback for Inactive SIM Resource Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-SIM terminal technologies do not adequately address the scenario where one SIM is in an inactive state and receives paging signaling from a second system, potentially causing interference with active communication and resource wastage due to repeated paging attempts.
Innovation Solution
A method and apparatus for a multi-SIM terminal to determine whether to respond to paging messages for inactive SIMs, sending target indication information to the network to avoid unnecessary paging responses, thereby informing the network of the inactive state without triggering incorrect operations or resource waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal sends a paging response for the inactive SIM, then the paging is acknowledged, but it may interfere with active communication and cause resource waste
Solution Approach 1:
The patent changes the state parameter of the SIM from inactive to active condition for paging response. When SIM1 is in active communication, the terminal changes the behavior parameter of SIM2 from responding to paging to not responding, thereby avoiding resource waste while maintaining reliable communication for the active SIM.
2Productivity
If the terminal does not send paging response for inactive SIM, then active communication is maintained, but the network cannot determine if the SIM received the paging message
Solution Approach 1:
The patent implements a feedback mechanism where the terminal sends indication information to the network to feedback the status that SIM2 received the paging message but will not respond due to SIM1's active communication. This resolves the information loss problem while maintaining communication efficiency.
3Reliability
If the terminal implements different processing methods for different SIM states, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic processing where the terminal's paging response behavior changes based on the real-time state of SIMs. When SIM1 is inactive, SIM2 responds to paging; when SIM1 becomes active, SIM2 stops responding. This dynamic adaptation improves reliability without requiring complex static configurations.
Data Source
AI summary
The present disclosure provides methods and apparatuses for sending information, and storage media. The method for sending information includes: in response to determining that a first SIM is in service communication and receiving a paging message for paging a second SIM in an inactive state sent by a target base station through paging signaling, determining whether to perform a paging response, where the target base station is a base station covering an area where the second SIM is currently located; and in response to determining not to perform a paging response, sending target indication information to the target base station by the second SIM, where the target indication information is for informing a network side that the second SIM has received the paging message, but does not perform a paging response.
